Ok thanks for the advice. I'll go and check out those x1900xt's then. I've heard that their stock coolers are a bit loud. Is this true? What replacment coolers are recommended?

The Artic Silencer is always recommended. They are the best air cooling solution for all graphic cards in the market. Great cooling effects and extremely quiet. Even you had 2 of these fans set up in your system(eg. Crossfire set up), the noise level would still lower than your CPU fan.

hmmm.... i would still go for the 7900GT. a small mod and it clocks past 7900GTX speeds for £168... kicks 1900XT butt

Or not..

The 1900xt 256 is the faster buy for the money, but yes it is noisy. If you're concerned with that and/or play mostly openGL games the 7950 isn't to be scoffed at. Either way you'll end up with a good choice

well surley if what that guy says about it modding to a 7900 gtx then its not as fast, as the 7900 gtx is a level above...
